Get and print directories from $PATH in bash

The script that I have to write must find the directories from the $PATH variable and print only the ones that end with an i.

How am I thinking about doing it

• Get each directory from the variable with a for loop.
• Find the length of each directory and get the last character from each using a substring
• Use an If condition to print the directories that end with an i

Problems

• The directories are not separated with a new line and I can't read them using a for loop.

Any ideas on how to get over this problem,or can you think of something more appropriate.

You can use this BASH one-liner for that job:

(IFS=':'; for i in $PATH; do [[ -d "$i" && $i =~ i$ ]] && echo "$i"; done)

• IFS=':' sets input field separator to :
• $PATH is iterated in a for loop
• Each path element is tested if it is a directory and if it is ending with i using BASH regex
• If test passes then it is pritned
